2. Recommended Design Flow
Intel® recommends that you create an example top-level file with the desired pin outs and all interface IP instantiated, which enables the Intel® Quartus® Prime software to validate your design and resource allocation before PCB and schematic sign off.
The following figure shows the design flow to provide the fastest out-of-the-box experience with external memory interfaces in Intel® FPGAs. This design flow assumes that you are using Intel® IP to implement the external memory interface.
